Dems have a good chance to take the house in 2026.
I think Reps will keep the senate by a razor thin margin. It looks like Collins will lose in Maine and whoever replaces Tillis in NC will also likely be a democrat. That would bring 53-47 down to 51-49.
I'm not sure what impact the BBB will have. Current polls show that it's wildly unpopular but I think a lot of that is due to democrat scare tactics. A lot of people have been led to believe that Food stamps, Medicaid, and even Medicare are at risk but the reality is nobody loses their benefit except for illegals and able bodied people who refuse to work. People might feel better once they discover that their benefits weren't impacted.
Democrats will continue to run on Reps giving huge tax breaks to billionaires even though there was no such thing. They'll run on tax hikes for the rich but they won't say how much they'll be able to lower the deficit. The fact is they'll propose more new spending that would offset any tax hikes. Of course it won't matter because Trump would veto such efforts.
As usual it all comes down to the economy. Republicans have a chance it unemployment remains below 4.5% and interest rates decline.
